Fluoropolymer alloys made of melt fabricatable extra-high-molecular weight fluorinated ethylene-propylene copolymer (EHMW-FEP) and one or more other polymers. In fluoropolymer alloys made of EHMW-FEP and polytetrafluoroethylene, the weight percentage of the former is 0.1-99.9% and the latter is 99.9 ...

A process for the preparation of sulfonated polyurethane-urea polymers, which are useful film to film laminating adhesives for flexible packaging in which the urethane-urea polymer component has no amide linkages. The water-based sulfonated polyurethane prepolymers are processed at reduced temperatu ...

Aqueous dispersion adhesives of anionic polyurethanes which have high heat resistance and low activation temperature, even when employed without addition of a cross-linker. The polyurethane is the reaction product of an isocyanate terminated polyurethane prepolymer, and water. The polyurethane prepo ...

Improved aqueous anionic polyurethane dispersions with a high crystallization rate, low heat activation temperature, high green strength, stability at low pH, which show good compatibility with other water based polymers and with crosslinkers. The aqueous anionic polyurethane dispersions have high h ...

Aqueous dispersion adhesives of anionic polyurethanes which have high heat resistance and low activation temperature, even when employed without addition of a crosslinker. The polyurethane is the reaction product of an isocyanate terminated polyurethane prepolymer, and a chain extender. The polyuret ...

This sealing unit is composed of sealing element made from super high mol. wt. polyperfluoro ethylene propylene copolymer resin, supporting ring, pressing screw nut, upper supporting ring, lower supporting ring and cylinder of sealings, all of which other than the sealings are made of non-ferrous me ...

The blends of fluoroine-containing plastic alloy are composed of thermoplastic-processable super high molecular weight copolymer of tetrefluoroethylene and hexafluoropropylene with one or more kinds of other plastics,and fillers can be added. The composition of super high molecular fluoroine-contain ...

This invention refers to a method of producing title resins, which have characteristics with meltviscosity higher than 1.0X10 to the power 6 poise and mol. wt. higher than 2.0X10 to the power 5, 12-30 wt.% of perfluoro-propglene and being apt to thermoprocessing. Liquified hexafluoropropylene is use ...

The fluoroplastic alloy consists of poly-perfluoride ethylene or propylene with super high molecular weight made of thermo plastics of arbitary weight ratio, and one or more kinds of other plastics, such as the copolymers of polychloro-trifluoro-ethylene, polyvinylidene fluoride, tetrafluorocthylene ...
